Strand material, such as yarns, tow or film, is processed through a fluid treatment apparatus which utilizes a polylaminar stack structure to form an elongate strand processing duct which has a strand inlet, a strand outlet, and a duct cross section which changes both in breadth and in height between the inlet and outlet.

Polylaminar apparatus for fluid treatment of yarn

A fluid yarn processing jet of trilaminar construction wherein a recessed discontinuous inner lamina forms a yarn processing duct which has at least one fluid entry port thereto and wherein an outer lamina is readily removable to facilitate the placement of yarn within the duct. All exterior edges in the vicinity of the duct which are resultant from the recessing of the inner laminar are rounded so as to prevent yarn damage.

Apparatus for fluid treatment of yarn

Process and apparatus for crimping filamentary material, the process comprising forcing hot fluid entrained yarn into a crimping chamber in one direction, forcing cold fluid into the crimping chamber from an opposite direction and exhausting both fluids from the crimping chamber either radially and/or axially. The apparatus employs a crimping chamber having axially aligned entrance and exit portions and means within the crimping chamber for radially exhausting fluids.
